part of it, it's a joke, u know lar :bsmilie:
That's what I mentioned in the previous posting majority of it who don't know how to answer simply avoiding to answer it by posting some immature, nonsense answer and more to come.
And I agreed with you, and this made sense, mostly who don't really use all of it but here they still try to reply with no answer which is simply avoiding.
The rest: come post more nonsenses answer, that would depict how mature you are.

Kid how many of these lens do u personally owe? I fail the test and have alr sold 6 of them.i think i shld sell the last one since i dont know them well enough. All these lenses, range and aperturre all diff for diff needs and budget. All lens has a reasonable sharpness. On paper print i cant see any diff except when pixel peep on lcd. Why dont u just come out with a thread fr 15mm fe to 800L and ask which is the sharpest and rank them?

And is so duh to compare sharpness of prime against a zoom and a L against a non L. You have lens as cheap as 500+ to 3k++. you got do science in sch? There is no consistency or base to compare. You dont compare apple with orange. I dont deny the fact i am a amateur who happens to have more cash outflow to try new lenses or more expensive lens.
Immature to me is those whinners who comes online trying to self justify to themselves can buy cheaper lens to get same quality simply because they cant afford the more expensive version. To me is got money buy, no money buy what you can and dont need to come up with all the funny reasons to self justify. But i am sayiing expensive = good as i have notice with my gear measurbator( sorry ian). So come on what is the purpose of this thread?

To TS,
This poll is being questioned as there is no basis of comparison among the choices; thus it is flawed from the beginning.
Also, as mentioned, not many people have enough experience among the choices to make an objective conclusion (if that is even possible). It is more likely an indication of the popularity of the lens, one that is used more times or owned by people is more likely to get the vote.
Another point is perhaps the poll serves no purpose, what can one do with the data (ignoring that that fact that it is flawed)? We don't buy a 135mm because it tops the poll in sharpness, we buy it because the range suits our purposes.
In your shoes, the replies from others that border on ridicule is a bit hard to swallow. It is so easy to indulge in one upmanship on the internet, and people sometimes try to outdo each other by making a single target look foolish; and unfortunately this poll is an easy target.

Hi, 50mm f1.2 is the sharpest as it is the lowest f1.2 and only 50mm, the easiest to make and should therefore be sharp across the frame wide open and equally sharp on stopping down to the lowest. There should be no much aberrations and reflections after corrections compared with the others which are more difficult to make and correct and thus give problems to sharpness.
(emphasis added)
That says it all really.
The reason I've kept going on and on in this thread is there are still people popping in to vote when they shouldn't be voting, and people who feel comfortable pronouncing the 50/1.2 the sharpest with no real experience with it one way or the other.

I think it's worth consolidating all the replies and see which one is the sharpest. I like yours... but I also like Kit's. And I think that pix of the legendary 35mm f/128 a sharp answer also.
Of course, not forgetting the sharp tongued Jed and nai meh.
:thumbsup:
Realise my last post isn't clear. Go to www.the-digital-picture.com and select anyone of the eight lenses. You'll find the sharpness test standard done for that lenses ( not MTF ) by clicking on ISO 12233 Crops.Again you can select another lenses and just do a side by side comparison by moving the mouse in and out of the pic frame to see the 2 different lenses result based on same or different aperture. They even show center, mid and corner sharpness. So depends on which section is of interest, you can then make the comparison.I think if those who voted so happened to have the sharpest lenses but with different combination of others, the poll will skewed towards the "real winner". I think the result of the poll in this sense is quite accurate ie 135L.:bsmilie:I happen to have 5 out of 7, but i vote because I compared the results from that website

Perhaps, but almost as many people voted for zooms (34 compared to 38 for the top result) as being sharper than any of the primes...
Yes, those who don't know the answer, avoiding to answer, giving childish answer literally tarnishing its reputation, in reality their own one so to speak.
If one disagree, one should show the utmost professional way of answering the question being the leading forum int SG.

200mm f2.0L IS is the sharpest by far. Since this is not in the list, 135mm comes next.
Frankly, what harm does this poll does that trigger all the masters & shi-fu in stepping in and slamming it so hard.. I really missing the point here. If all of us agree that sharpness is subjective, then subjective matter is a good way to poll. So let's relax and take it with some fun...
I own all the lens at one time or other except one (24-70/2.8, but I did test out a few copies before). Frankly, the poll result is pretty close to my own perception. 135 f2 is definitely my favorite in terms of image sharpness, and 85 1.2 is pin-sharp as well, even wide-open. 50 1.2 is something you need to spend sometime calibrate, once you got it right, it's sweet. 85 1.8 is sharp. The rest.... so so lah.

It's not just the subjectivity, it's the fact that very very very few people are in any sort of a position to give a reasonable response.
If I asked you, which of the following lenses are the sharpest:
Nikon 50/1.4
Canon 50/1.4
Pentax 50/1.4
Olympus 50/1.4
Leica 50/1.4
Zeiss 50/1.4
Yashica 50/1.4
Sigma 50/1.4
How many people do you think are qualified to answer that question? How many people do you think have used more than one of those lenses, and how does using one, or even seven, qualify you to have a pop at answering which is the sharpest?
Hopefully your reaction to that is, but they're all different brands how can you expect people to have experience with them, so how can they tell which is the sharpest?
Just because all the 8 lenses are all Canon lenses, rather than from different random brands, doesn't suddenly mean the majority of people are able to tell. This poll might as well be about some complex mathematical equation or scientific theory that you need a PhD to understand, yet so many people are happy to put forward their own theory of relativity.
123, that's one hundred and twenty three people, at the time of this writing, apparently feel qualified to tell which of 8 lenses is sharpest. Have these people actually used these lenses to be able to tell subjectively which is sharpest, nevermind objectively?
If you haven't tried something, you can't even subjectively comment about that something.
Fun maybe something along the lines of "which lens of the following would you most like to own?" That's subjective, but a question for which people are qualified to answer.
And as for the poll being close to your own perception... I ask again. 45 people, that's more than 1 in 3, think a zoom lens is the sharpest lens in that lot. Does that tally with your perception?
How much of everyone's "perception" is conditioned by totally unscientific and baseless polls exactly like this one? How many of those 50 people that voted for the 135/2 have never even picked it up before in their lives?

The poll is HIGHLY INACCURATE because......
the total percentage adds up to more than 100% at 140+ :bsmilie: other than this the result is quite close to laboratory test, unless the ISO standard of testing done is crappy. Next time for those who vote must show their possession by posting the photographs.:bsmilie:
